Which range to use in a Prometheus rate query is already a bit of rocket science. When Grafana enters the game to visualize the result of such a query, things get even more interesting. In most cases, you’ll end up with a dynamic range, but navigating the many available settings for it is sometimes a bit daunting. But do not despair, this talk will teach you all you have to know, even in case when you add to the mix recording rules, which are blissfully ignorant of any dynamic range requested by Grafana. If all goes well, we can even inaugurate a nifty little new feature in the Prometheus data source that will improve your rate visualizations even more.
